Trigger builds from CI

Learn how to trigger builds on EAS for your app from a CI environment such as GitHub Action and more.


This document outlines how to trigger builds on EAS for your app from a CI environment such as GitHub Actions, Travis CI, and more.

Before building with EAS on CI, we need to install and configure eas-cli. Then, we can trigger new builds with the eas build command.

Prerequisites

Run a successful build from your local machine

To trigger EAS builds from a CI environment, we first need to configure our app for EAS Build and successfully run a build from our local machine for each platform that we'd like to support on CI.

If you have run eas build -p [all|ios|android] successfully before, then you can continue.

If you haven't done this yet, see Create your first build guide and return here when you're ready.

Configure your app for CI

Provide a personal access token to authenticate with your Expo account on CI

Next, we need to ensure that we can authenticate ourselves on CI as the owner of the app. This is possible by storing a personal access token in the EXPO_TOKEN environment variable in the CI settings.

See personal access tokens to learn how to create access tokens.

(Optional) Provide an ASC API Token for your Apple Team

In the event your iOS credentials need to be repaired, we will need an ASC API key to authenticate ourselves to Apple in CI. A common case is when your provisioning profile needs to be re-signed.

You will need to create an API Key. Next, you will need to gather information about your Apple Team.

Using the information you've gathered, pass it into the build command through environment variables. You will need to pass the following:

  • EXPO_ASC_API_KEY_PATH: The path to your ASC API Key .p8 file. For example, /path/to/key/AuthKey_SFB993FB5F.p8.
  • EXPO_ASC_KEY_ID: The key ID of your ASC API Key. For example, SFB993FB5F.
  • EXPO_ASC_ISSUER_ID: The issuer ID of your ASC API Key. For example, f9675cff-f45d-4116-bd2c-2372142cee09.
  • EXPO_APPLE_TEAM_ID: Your Apple Team ID. For example, 77KQ969CHE.
  • EXPO_APPLE_TEAM_TYPE: Your Apple Team Type. Valid types are IN_HOUSE, COMPANY_OR_ORGANIZATION, or INDIVIDUAL.

Trigger new builds

Now that we're authenticated with Expo CLI, we can create the build step.

To trigger new builds, we will add this script to our configuration:

Terminal
npx eas-cli build --platform all --non-interactive --no-wait

This will trigger a new build on EAS. A URL will be printed, linking to the build's progress in the EAS dashboard.

The --no-wait flag exits the step once the build has been triggered. You are not billed for CI execution time while EAS performs the build. However, your CI will report that the build job is passing only if triggering EAS Build is successful.
Travis CI

Add the following code snippet in .travis.yml at the root of your project repository.

travis.yml

  include:
    - stage: build

        - npm ci
        - npx eas-cli build --platform all --non-interactive --no-wait
GitLab CI

Add the following code snippet in .gitlab-ci.yml at the root of your project repository.

          - npm ci
          - npx eas-cli build --platform all --non-interactive --no-wait
CircleCI

Add the following code snippet in circleci/config.yml at the root of your project repository.

.circleci/config.yml
version: 2.1

      - image: cimg/node:lts
    working_directory: ~/my-app

jobs:
  eas_build:
    executor: default
    steps:
      - checkout
      - run:
          name: Install dependencies
          command: npm ci
      - run:
          name: Trigger build
          command: npx eas-cli build --platform all --non-interactive --no-wait

workflows:
  build_app:

      - eas_build:
          filters:
            branches:
              only: master
GitHub Actions

Add the following code snippet in .github/workflows/eas-build.yml at the root of your project repository.
